Abstract：Deep geological storage of CO2 can provide an essential solution to mitigate greenhouse gas emissions from the continuous use of fossil fuels.However,the cost and energy consumption of CO2 capture is high at present.About 60% of carbon capture and storage(CCS) cost is for the carbon capture which causes a bottleneck in advancement of CCS in China.High levels of CO2 from coal chemical plants pro-vides sufficient CO2 for full-chain CCS implementation.The total amount of high concentration CO2 that will be emitted( or is being emit-ted) by the coal chemical factories approved by the National Development and Reform Commission is up to hundred million tones per year. If all projects could store CO2 underground,it would be of great significance for mitigating greenhouse gas emissions.Basins located in North China are characterized by several sets of reservoir-caprock strata which is suitable for CO2 storage.Some oil fields are potentially suitable for CO2 enhanced oil recovery(EOR).The short distance between the high concentration CO2 sources and potential storage sites reduce transportation cost and operational.So high purity sources coupled with EOR or aquifer storage offer China the opportunity to accomplish beneficial CCUS globally.
